本文介绍一新研制的恒温槽,使标准电池能在良好的条件下保管。2748型标准电池用恒温槽是可容纳六个饱和标准电池的可移动式空气槽,在周围温度为10～27℃时,槽内温度变化保持在0.01℃以下。为了在得不到交流电源的搬运过程中也保持恒温,内附Ni—Cd电池,充足电后它能工作13小时。试验结果表明,该恒温槽具有以优于5ppm的准确度来保持直流电压标准的良好性能。文中也叙述了关于根据标准电池进行电压标准管理的问题。
This article describes a newly developed thermostat bath that allows standard batteries to be stored under good conditions. The Model 2748 Standard Battery Thermostat is a portable air tank that holds up to six saturable standard cells and maintains a temperature change below 0.01 ° C at ambient temperatures of 10-27 ° C. In order not to get the AC power supply during the transfer also maintain a constant temperature, with Ni-Cd batteries, fully charged it can work 13 hours. Test results show that the bath has the good performance of maintaining the DC voltage standard with an accuracy of better than 5 ppm. The article also describes the issue of voltage standard management based on standard batteries.
